That looks like msg.payload.value[0] to me.

In that second example, Impostata looks like an array. If that is the case, you have to select a single value from that array.

Not possible to do it within a function, you should use either a Dashboard text node, or a UIBuilder template.

Simplest way is to install the Dashboard nodes if you haven't yet, and take a text node. Check the documentation and the website, there are a lot of examples.
